Multiple canal morphology in the maxillary first molar: case reports.
The presence of several canals in each root has been established as a normal morphology of the root canal system. Two case reports are presented to describe maxillary first molars with multiple canal system morphology in the palatal root. Both teeth exhibited two canals in the palatal root, although with different morphologic manifestations. One of the molars exhibited two canals in the mesiobuccal root as well.
